Title: Improvements in or appertaining to riveting hammers
IPC: B21J15/10
Filed: 1941-11-21
Abstract: 553,542. Riveting. STANIER, W. A., GREAVES, H., and SMITHYMAN, G. T. Nov. 21, 1941, No. 14972. [Class 83 (iv)] A riveting hammer is fitted with an attachment to convert it into a self-contained abutment machine. The yoke shaped abutment e has the shorter leg e<SP>1</SP> fitted with parallel rods f connected at their outer ends by a block n. The rods are guided in brackets g, g', clamped at g<SP>3</SP>, g<SP>2</SP> to the barrel of the hammer. The bracket g<SP>1</SP> is in two parts the plane of division passing through the axes of the rods. The bracket g is split only at its barrel embracing part. A crosshead h rigidly connected to the rods confines springs j between itself and the bracket g to control the pressure with which the abutment is held against the work. The block h may limit the extent of the advance. A hand lever k pivoted to the bracket g is linked at m to the block h to provide for compressing the springs, to an extent limited by contact of the block n with the bracket g<SP>1</SP>, while the machine is being applied to the work. The holding pressure is varied by changing the springs j. In a modification the rods are of two diameters to provide shoulders to contact the bracket g<SP>1</SP> and the block h is adjustably mounted by screw threads and nuts and screws to control the amount of the spring pressure. In a further modification only one rod is employed mounted centrally between two guide plates sliding in dovetail guides on the brackets.

The discs may be made of sheet metal and may be provided with an inner face of resilient material, certain kinds of polyamides being suitable for the purpose. The discs may be constructed of resilient material and may be fixed on a spindle by means of a second smaller disc fixed to the spindle.

A liquid fuel atomizer comprises a rotary cup a, an axial fuel supply duct c and one or more centrifugally operable valves f arranged within the cup for admitting fuel from the duct to the cup. Each valve comprises a spring-loaded piston within a hollow arm e extending radially from a boss d secured to the end of the supply duct c which is constituted by an axial bore in the driving spindle b for the cup. The inner ends of the hollow arms communicate with the supply duct c and when the spindle rotates the valves allow the fuel to pass to annular grooves i from which it flows through tangential ports to the cup. A disc h is secured to the outer end of the boss d and forms between its periphery and the edge of the cup an annular outlet for the atomized fuel. The spindle is driven by an electric motor or by a turbine comprising a rotor k driven by the liquid fuel. The cup is mounted in an axial air passage r at the entrance end of the combustion chamber q of a gas turbine or jet engine.

Abstract: 440,487. Reflectors. MEY, E. G. DE, 34, Martin Place, Sydney, Australia. May 22, 1934, No. 15247. Convention date, May 19, 1933. [Class 75 (ii)] A reflector adapted to produce from an ordinary artificial light source a soft, glareless, and natural light, and suitable for use in a reading, vehicle, or like lamp, comprises a plurality of separate and interchangeable sections of coloured glass or like material, each with a rear reflecting surface, the sections being arranged symmetrically around the light source so that the direct and reflected rays of light both fall on the surface to be illuminated. The sections may be all of one colour or of different colours. For example, a daylight effect may be obtained by using 7¢ blue sections, 1 yellow section, 1 red section, and ¢ green section. In the form shown, the sections 6 are made of blue glass with a silvered or bronzed rear surface protected by a black outer coating, and are mounted within a pyramidal-shaped metal casing 7 by means of lower flanges 8 and upper tangs 9. The casing may be ornamented or coloured and it is suspended by means of a spider bracket 12 having a split sleeve 13 slidably mounted on a tube 14 and locked in position by means of a wing nut 15. The upper end of the tube carries a suspension hook 17 whilst its lower end carries an ordinary electric lamp bulb 11 producing yellowish light. Changes of colour tone may be obtained by adjusting the position of the reflector with respect to the bulb. The tangs 9 may be replaced by clips bolted to the casing 7, and the wing nut 15 may be replaced by a ratchet and pinion. The Specification as open to inspection under Sect. 91 comprises also the use of a light source which is fixed relative to the reflector, an electric lamp bulb with its lower end coloured, a condenser at the outlet end of the reflector, glass or like sections which are formed integrally with one another, and additional reflectors at the top or side of the main reflector. This subject-matter does not appear in the Specificacation as accepted.

Title: Improvements in or relating to safety devices for hydraulic brakes for motor vehicles
IPC: B60T11/32
Filed: 1954-05-25
Abstract: 739,888. Hydraulic brakes. YARATAN, H., and AKGULER. H. May 25, 1954, No. 15401/54. Class 103 (1). In a safety device for hydraulic brakes of a motor vehicle a hollow receptacle body 1 having four valve ports 2 and a flanged face 10 is secured to the output end of the master cylinder 13 and the lower portions 4 of the valve ports 2 are tapered and in communication with conduits 7 which are connected to the wheel brake cylinders of the vehicle so that when the brakes and the conduits are operating normally, the hydraulic pressure of the brake fluid in inclined bores 8 keeps balls 5 pressed against the restricted portions of the bores 8 where the balls 5 are stopped in the inoperative position of the brakes as illustrated. When the brakes are operated by pressure on the foot brake pedal, brake fluid is forced into the braking system by the piston 14 of the master cylinder 13 to cause the balls 5 to be carried a limited distance up the bores 8, the balls returning to their original position when the brakes are released. Should a fracture occur in any of the conduits 7 to the wheel brake cylinders, no pressure will be developed in that pipe line when the brakes are operated and the brake fluid will be displaced under pressure into the bore 8 to bring the ball 5 into the valve port 2, thus closing the port and that of the conduit 7 leading to the faulty brakes. In this way the other brakes remain fully operable. The internal space of the receptacle is filled with brake fluid through a conduit 23 leading from a reservoir when the piston 14 is withdrawn to its extreme inoperative position.

Filed: 1924-06-26
Abstract: 218,311. Lemlyn, N. June 29, 1923, [Convention date]. Switches, quick-action, have a fixed rectangular frame consisting of uprights 6 connected by cross bars 7, 8 bearing sets of fixed contacts 18, 19 within which slides a vertically movable frame carrying the movable contact members 11. The movable frame comprises rods 1 connected' at their ends by cross bars 2, 3, the latter of which carries between pillars 4 a pin 5 for attachment to a pivoted operating lever. Arranged to slide over the rods 1 and a central rod 21 is a contact-carrying block 10, springs 12, 13 being interposed between the sides of the block 10 and the cross members 3, 2. Pivoted to the fixed frame are two pairs of latches 14, 14<1> the hooked ends of which are pressed inwards by springs 15. As the switch is moved from its lower contact position (Fig. 2) to its upper position the spring 13 is compressed until the bar 2 engages the lateral projections 17 on the lower pair of latches 14', after which the block 10 being released is moved upwards with a quick action. The hooked end 15 of the upper pair of latches 14 engage the block 10 in its upper position, and a similar snap action occurs in the reverse movement of the switch operating lever.
